It isn't a secret how important a good night's sleep is. Many successful leaders around the world, including Margaret Thatcher and Twitter founder Jack Dorsey, have claimed that in order to operate efficiently throughout the day they need merely four to five hours a night.
However, this may not be the case. According to Dr. Tara Swart, international neuroscientist and CEO of the Unlimited Mind, only one to two percent of the entire population can operate throughout the day on four hours sleep. The other 98 percent of us require the recommended seven to eight hours a night.
Problems associated with not getting the recommended amount of sleep, according to Dr. Swart, include a lack of social ability and emotional stability. Sleep disturbance could also lead to a drop in your IQ points, and studies have shown that if we miss just one night our IQ drops by one standard deviation. Dr. Swart says that this could cause individuals to 'operate as if you've got a learning disability'.
Dr. Swart also argues that memory problems, issues with decision making, lack of creativity and regulating your personal emotions are the first to be targeted by lack of shut-eye.
